how to determine which is the formaldehyde content detection of environmental protection flooring

as the main decorative material of home decoration and its position in decoration, people pay more and more attention to flooring. While choosing elegant and friendly styles, people pay more attention to the environmental protection performance of the floor and the corresponding environmental protection indicators

in the mixed and dazzling floor market, how to determine which are environmentally friendly floors? What is the decisive indicator of floor environmental protection "formaldehyde emission"

national standard for formaldehyde emission

there are three detection methods for formaldehyde emission in China: perforation quenching method, climate box method and dryer method, among which the dryer method is the most accurate method to reflect the environmental protection performance of the floor, and it is also the content of the implementation of the new national standard

according to the new national standard in July 2002, if the formaldehyde emission of the floor is less than or equal to 1.5mg/L, it is in line with the provisions of the new national standard and the requirements of indoor environmental protection and health

gold content of the test report

the test report is the most intuitive material to reflect the environmental protection indicators of the floor. Therefore, when buying a floor, the floor merchants will always take out different test institutions to issue a report sheet marked with formaldehyde emission, some may be marked with 0.08mg/m3, and some may be marked with 0.8mg/L. the value units recorded in the two formaldehyde content test reports are different. Who is more environmentally friendly? It seems that the former, in fact, 0.8mg/L is more environmentally friendly

before July, 2002, formaldehyde emission expressed in different units, which brought a lot of trouble for people to choose and buy floors. In July, 2002, the new national standard was officially implemented, and all floors whose formaldehyde emission did not meet the requirements of the new national standard or had not been tested by the new national standard could be regarded as non environmentally friendly floors

therefore, you can purchase environmentally friendly flooring in accordance with the requirements of the new national standard to reduce unnecessary trouble

the test report of the floor can be divided into: national supervision and random inspection, entrusted sampling inspection and submission for inspection. National supervision and random inspection refers to that the national quality supervision and testing institutions regularly and irregularly conduct sampling inspection on the floor products sold in the market, publish the test results in the media, and urge the unqualified floor products to improve their quality

entrusted sampling inspection is a form of enterprise self-discipline in which flooring enterprises actively invite national quality supervision and testing institutions to conduct random sampling inspection of all their inventory products. The inspection report comprehensively reflects the quality of the brand

some advice on buying flooring

in view of the concealment of the environmental protection performance of the floor itself, people often judge whether the floor is environmentally friendly through the inspection report of the brand floor

it is recommended that you pay attention to the contents of the corresponding columns of "inspection category" and "inspection basis" when looking at the inspection report. Generally, the inspection category is national supervision and inspection or enterprise entrusted sampling inspection, and the reliability is higher than that of submission for inspection. The formaldehyde emission of qualified products should be less than 1.5mg/L

in addition, the unit of formaldehyde emission can also be used to determine whether to implement the new national standard
